In Power Master 1: A Strange Journey, a Book of Laser is an equipable weapon that can only be bought from the Blacksmith in Yora. According to its description, it is created by fusing a Book of Lightning and a Book of Wind together. Book of Laser deals both Lightning- and Wind-based damage and increases the wielder's Attack by 70. It makes the wielder strong against Ice-, Lightning-, and Wind-based moves, but weak to Fire- and Stone-based ones, with the user taking 400% more damage from Stone-based attacks. It also has a 40% chance of inflicting either a Paralyzed or Blown status ailment on the enemy.
